I am selling my Hewlett Packard HP-25C calculator with continuous memory. I am the original owner of this calculator, I bought it at Macy’s in New York in late 1976. I also have the original case, charger, owner’s handbook, and applications book. The calculator works fine, and is in nice condition. All the keys and display work. The batteries should be replaced, they will only hold a charge for a few minutes (they are 43 years old!). As a bonus, I will also includ...e an HP-31E and case. The HP 31E also works well. Great calculators to add to your collection. See pictures. Note: This is a relisted auction that was posted earlier (# 233240946256) I had to relist it because of an error in the "Item specifics" section. Everything else is the same. Sorry for the confusion
